Printing PLA at 220, bed 70
Base layers print extremely well.
However, at variable time in the print (never far into it) the filament starts to thin out then in rapid succession the bukobot stops with the extruder sitting on the print.
Have reloaded software, flashed firmware, changed usb cable, turned off all electrical sources around it. Tried different files as well.
When the next print is attempted the pva flows freely and there is no temperature drop to explain a jam.Drive gear looks ok
